The '''HTC EVO 4G''' (trademarked in capitals as EVO 4G) is a [[smartphone]] developed by HTC Corporation and marketed as Sprint's flagship smartphone, running on its "4G" network, which is currently a non-standardized platform. The smartphone launched on June 4, 2010.<ref>{{cite web|url=http://now.sprint.com/evo/?ECID=vanity:EVO |title=Sprint HTC EVO 4G |publisher=Now.sprint.com |date= |accessdate=2010-06-24}}</ref><ref>{{cite news | title= Is Sprint Too Early With The HTC EVO 4G Phone?

== History == |
|||
=== Development === |
|||
During development, the device was known as the HTC "Supersonic", which was leaked throughout the internet and was already known as a variant of the HTC HD2 running Android. |
|||
=== Release === |
|||
The EVO was released on June 4, 2010 in the United States through Sprint.<ref>| publisher=ChannelWeb | date=25 March 2010 | url= http://www.crn.com/networking/224200297 | accessdate=2010-03-26}}</ref> The device became the top-selling launch day phone on [[Sprint Nextel|Sprint]], surpassing the [[Palm Pre]], [[Samsung Instinct]] and [[Motorola Razr V3]].<ref>{{cite web|url=http://www.engadget.com/2010/06/07/htc-evo-4g-overtakes-palm-pre-for-best-selling-launch-day-on-spr/ |title=HTC EVO 4G overtakes Palm Pre for best-selling launch day on Sprint |publisher=Engadget |date= |accessdate=2010-06-24}}</ref> |
|||
== Features == |
|||
The HTC EVO features hardware very similar to the [[HTC HD2]], a smartphone running Windows Mobile. The device is sometimes referenced as the Android version of the HTC HD2 although a variety of features are only available on the EVO 4G ([[video calling]] for example). |
|||
=== Screen and input === |
|||
Unlike many other smart-phones in the consumer market, the EVO has a large 4.3-inches (480-by-800) TFT LCD [[capacitive touch screen]] display with a pixel density of 216 pixels per inch (ppi). The display is designed to be used with a bare finger or multiple fingers at one time for [[multi-touch]] sensing. Most gloves and styli prevent the necessary electric conductivity required for use on the capacitive display. |
|||
The EVO has a balanced hardware-software user interface, featuring seven hardware/touch sensitive buttons, four of which are on the front of the device. Input and interaction with the device is balanced between the hardware and software user interface and in most situations require users to use hardware/touch sensitive buttons often throughout Android OS. Like most Android devices, the EVO features four main touch-sensitive buttons on the front of its device which are the Home, Menu, Back, and Search. The Home button returns users to the Sense Home screen. The Menu button gives users menu options in various applications although it can also be used for other purposes, the Back button is used to return users to the previous page or screen the user was on, and the Search button mainly allows users to search through their phone although it too can also be used for other purposes in various applications. Unlike most smart-phones though, the device does not feature a hardware ringer switch.<ref>http://www.goodandevo.net/2010/06/how-to-quickly-silence-your-htc-evo-4g.html</ref> Situated on the left spine are the volume adjustment controls which controls the volume. A multifunction sleep/wake button is located on the top of the device which serves as the unit's power and sleep button and also controls phone calls. The touchscreen furnishes the remainder of the [[user interface]]. |
|||
The device responds to four sensors. A [[proximity sensor]] deactivates the display and touchscreen when the device is brought near the face during a call. This is done to save battery power and to prevent inadvertent inputs from the user's face and ears. An ambient light sensor adjusts the display brightness which in turn saves battery power. A 3-axis [[accelerometer]] senses the orientation of the phone and changes the screen accordingly, allowing the user to easily switch between [[page orientation]] modes. A geomagnetism sensor provides orientation with respect to Earth's magnetic field. The proximity sensor and the accelerometer can also be used to control and/or interact with third party apps, notably games. The device also contains a temperature sensor used for monitoring the temperature of the battery. |
|||
The device also features a GPS chip allowing applications (with user's permissions) to report the devices location allowing for [[location-based service]]s and can also be useful to [[turn-by-turn navigation]] apps. |
|||
=== Processor and memory === |
|||
The EVO is powered by the Qualcomm QSD8650 chipset which contains a [[Snapdragon (processor)|Snapdragon]] ARM Cortex-A8 microprocessor clocked at 1 GHz and an embedded Adreno 200 graphics chip capable of up to 22 million triangles per second. |
|||
It features 512MB of eDRAM which allows for a smoother experience with Android OS, applications, and the HTC Sense user interface. The device also features 1024MB of built-in ROM which is mainly used for the system software. |
|||
=== Cameras === |
|||
The EVO features a rear-facing 8 megapixel camera capable of recording videos in 720p at 30 frames per second and dual flash which helps to illuminate objects in low-light conditions. In addition the EVO has a second camera on front of the device designed for use with video calling and for taking portrait images although it can also be used in other applications. |
|||
=== Storage === |
|||
Like many other Android mobile devices, the HTC EVO 4G features a microSD slot in addition to the built-in RAM which allows for user-expandable storage. The device supports microSD cards of sizes up to 32GB. With Android version 2.2+ (Froyo) available as an over-the-air upgrade, the OS supports applications which permit themselves to be installed on the SD card. |
|||
The device comes pre-installed with an 8GB Class 2 microSDHC card. |
|||
=== Audio and output=== |
|||
The rear of the EVO sports a speaker which is used for most applications like music, applications, and such as the main speaker. A loudspeaker is located above the screen which serves as an earpiece. The microphone is featured on the bottom of the phone which is used for phone calls and voice-commands although it can also be used in many other third-party applications. The unit has an HDMI-out port which allows users to output content on a HD television set. The Sprint Mobile Hotspot application allows users to share the device's mobile broadband on up to eight devices. |
|||
=== Smartphone connectivity=== |
|||
The EVO features a [[CDMA]] cellular radio that supports 4G EVDO, Revisions 0, A, and the as-of-yet undeployed B allowing faster download and upload speeds, and better power efficiency. As well as Beta WiMax, protocol known as 802.16e, which features speeds of up to 10Mbps on the downlink, and 1 Mbps on the uplink. Although the device is marketed as a 4G phone, there is no 4G standard set forth by the wireless standards committee yet. |
|||
=== Battery and power === |
|||
The device comes pre-installed with a 1500mAh Li-On rechargeable battery that is designed to be user-replaceable. The Battery is interchangeable with the batteries from the [[HTC Incredible]], [[HTC Touch Pro 2]], and [[HTC Hero]] (CDMA). |
|||
== Software== |
|||
The device sports the [[HTC Sense]] user interface which runs on top of the Android operating system and presents information through the Android desktop widgets and application, and includes launchers, app drawer, and lock screen replacements. Sense also brings a modified browser and home screen as well. The device first came with Android OS 2.1 "Eclair" although Android OS 2.2 "Froyo" has since been rolled out through OTA (Over-The-Air) making it the third device to officially run "Froyo" and the first to be officially rolled out by a US network.<ref>{{cite web |url=http://www.androidcentral.com/sprint-says-us-too-when-it-comes-froyo |title=Sprint says "Us, too!" when it comes to Froyo |accessdate=2010-06-26}}</ref><ref>{{cite web|url=http://www.evo4gforum.net/htc-evo-4g-apps/appbrain-app-market |title=HTC Evo 4G AppBrain App Market |date=2010-11-16}}</ref> |
|||
===Interface=== |
|||
The interface is based around home screen panels which in total are seven panels that allows user-customization. By default, the center home screen panel features a digital clock located on the top of the screen and weather animations of the current weather in the device's location, the remaining space in the bottom can be customized to the user's preference. The launcher which is located at the bottom of the screen displays icons to open the App Drawer, Phone application, and the ability to add widgets on the Android desktop, and is shown throughout all seven home screen panels. Users can switch from one panel to another by sliding left or right. A small bar which sits on top of the launcher represents the current panel the device is viewing. Pinching the home screen (or pressing the home button if the user is on the center panel) brings up Leap screen which shows thumbnail views of all the home screen panels and allow users to "leap" to another home screen panel easily. Unlike other custom user interfaces for the Android OS like Samsung's [[TouchWiz]] UI, HTC Sense does not allow users to disable or remove a panel. |
|||
Most of the input on the device is given through the touchscreen which understands complex gestures using [[multi-touch]]. Android's [[interaction techniques]] enable users to move up or down by a touch-drag motion of the finger. However the buttons on the front of the device will also require often use throughout various applications in Android OS as the buttons play an important part in the user interface. |
|||
==Criticism== |
|||
=== 30 frames per second cap === |
|||
Some users have experienced noticeable lag and/or slowness while using the phone.<ref>http://www.engadget.com/2010/06/10/htc-evo-4gs-graphics-capped-at-30fps/</ref> Various reports throughout the Internet indicated that the device may have a 30 frames per second cap explaining how some users experience [[lag]] with the phone at times. Initially it was first thought of as an "artificial" cap although it was later announced by an HTC representative that it was a hardware cap making software updates incapable of fixing the 30 FPS cap. HTC has also noted that the 30 FPS cap does not affect the usability and speed of the phone at all asking that users name at least one app or game that has been affected by the issue.{{citation needed|date=October 2010}} However, after the release of the kernel source code, it was shown by rooting the device and flashing a modified kernel, users could reach well over 50 FPS.{{citation needed|date=October 2010}} |
|||
Despite the repeated claims regarding the supposed hardware cap, HTC released an update on September 22, 2010 that, among other things, removed the 30 FPS cap.<ref>http://www.engadget.com/2010/09/24/confirmed-evo-4g-update-removes-framerate-cap/</ref> |
|||
=== Screen === |
|||
There have been many problems with the screen. Some of the first customers complained of screen separation, HTC acknowledged the problem and was able to limit the number of affected units. Another problem with the screen has been a bright spot in the lower area of the screen. Known by many as the B-spot because it is exactly where the B on the keyboard is. This bright spot is only noticeable when using a bright background. |
|||
=== Warranty === |
|||
The phone came with a 1 year warranty. To have the phone repaired in the US it needs to go to a [[Texas]] repair facility. HTC will not cover the cost of shipment to the repair facility. |
|||
== Design == |
|||
The EVO's design is derived from its Windows Mobile-based brother, the [[HTC HD2]] which also has a 4.3-inch multi-touch capacitive touchscreen, nearly the same slim profile, and the same placements of most general components and buttons. Although similar, the EVO has features which distinguish it from the HTC HD2 including the front-facing camera, circular-shaped camera, and touch-sensitive buttons instead of hardware buttons. Another feature is Android-specific buttons. The device has nearly the same dimensions, which are:<br> {{convert|122|mm|in|abbr=on}} ''(h)'' high<br>{{convert|66|mm|in|abbr=on}} ''(w)'' wide<br>{{convert|12.7|mm|in|abbr=on}} ''(d)'' deep |
